EQUALIZING DEVICE FOR VEHICLE-SPRINGS.

Specification of Letters Patent.

Patented Feb. 20, 1906.

Application filed February 28, 1905. Serial No. 247,721.

To all whom it may concern.-

Be it known that I, JOHN A. Born, a citizen of the United States, residing at I-Iannibal, in the county of Monroe and State of Ohio, have invented certain new and useful Improvements in Equalizing Devices for Vehicle-Springs, of which the following is a sp ecification.

This invention relates to that type of equalizing or brace devices for vehicles by which the elliptical springs ordinarily employed to support the vehicle-body upon the axles are greatly reinforced, so that said springs will always move vertically under all conditions of service, this being particularly important when the vehicle is going up and down hills, the tension upon the securing means of the vehicle-springs being increased to such an extent as to subject the springs to likelihood of breakage or injury.

An essential feature of the invention is comprised in the provision of means of the above class of simplified construction whereby the same may be manufactured at a minimum cost, so as to be more readily within reach of the average person using vehicles of any type.

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for efiecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment thereof is shown in the accompanying drawings, in

which- Figure 1 is a perspective view showing the embodiment of the invention in actual use. Fig. 2 is an end elevation. Fig. 3 is a side elevation.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The invention may be applied to any kind of vehicle, buggies, surreys, spring-wagons, or the like, and, referring to the drawings, the numeral 1 indicates the axletrees of a vehicle, the numeral 2 the body thereof, and the numeral 3 the elliptical springs usually interposed between the body and the axletrees. The front and rear axletrees 1 are connected suitably by means of spaced reaches 4, and substantially attached to the under side of the vehicle-body 2 is a supporting-plate 5, from which downwardly projects a U-shaped vertical extension 6, the lower portion of which is widened vertically. Extended laterally from the lower extremity of the vertical extension 6 is a pivot-stud 7, which is preferably integrally formed with the member 6. A bar 8 is pivotally mounted upon the stud 7, said bar being provided with an opening at a point between its ends to receive the stud and afiord a bearing thereupon. The bar 8 is arranged for movement in a vertical plane, and equalizing-bars 9 are connected at one end with opposite ends of the bar 8. The ends of the equalizing-bars 9 opposite those connected with the pivot-bar 8 have a pivotal connection with the axletrees 1. The bars 9 are bifurcated at the upper extremities thereof, the extremities of the bar 8 bcing received between the bifurcated portions of the bars 9, pivot-pins 1O connecting the several bars 8 and 9 aforesaid. Attachingplates 1 1 are secured to the inner sides of the axletrees 1, and spaced lugs are projected from the attaching-plates, receiving the lower ends of the equalizing-bars 9 therebetween, pivot-pins being also utilized to pivotally secure the bars 9 and the plates 11, above described. The disposition of the bar 8 is such that the equalizing bars 9 are arranged in substantially the same vertical plane, the above facilitating the equalizing action of these parts with reference to each other and to the parts to which they are secured.

The construction of the device as hereinbefore set forth is greatly simplified by the specific form of the various parts of the arrangement thereof. In actual operation movement of the axle-body upon the springs 3 either effects a pushing or pulling action of the respective bars 9, so that the springs 3 are securely braced against any play other than the vertical movement thereof, and the disadvantages of this action will be clear to those versed in the art to which this invention appertains.

Having thus described the invention, what is claimed as new is In combination, a vehicle embodying a vehicle-body, axletrees, elliptical springs supporting the body upon the axletrees, the supporting-plate 5 secured at its ends to the under side of the body of the vehicle and having its central portion projected downwardly to tion at the other end with the" attahing plates 11.

In testimony whereof I affix my sugnature in presence of two wltnesses.
